PURPOSE: A sender of a fuel gauge for an LPG vehicle is provided to improve the durability by preventing the damage due to abrasion when a rotator is driven by injecting a lubricating oil composition into the sender and prevent conductivity by preventing fine powder generated by the abrasion from being sticked to the ceramic board and preventing the ceramic board from contacting air by the oil composition, thereby preventing degradation of the performance. CONSTITUTION: In a sender of a fuel gauge for an LPG vehicle including a dashboard(52) in a case(51), a ceramic board(53) printed with an electric circuit, and a rotator(54) formed with a contact terminal(541), the case is formed in a sealed structure for preventing leakage of liquid and oil composition(50) is injected into the case to depositing a rear surface of the printed electric circuit of the ceramic board and the rotator, wherein the rotator contacts the printed electric circuit while rotating when the sender is operating, and the contact terminal assembled with the rotator rotates so that the injected oil composition carries out lubrication operation to make the contact between the contact terminal and the ceramic board smooth, thereby preventing damage due to abrasion.
